If you’ve ever picked up a product and took note of how it feels in your hand, you understand the power of sensory marketing. Manufacturers understand it too, which is why tactile information like the famous contour of a Coca-Cola bottle or the textured burlap packaging of Marfa brand soaps are unique and memorable. Some manufacturers also incorporate smell, as in the scratch-and-sniff packaging by Glade and Tide, while others rely on color, such as the trademark brown of UPS or the robin’s egg blue of Tiffany & Co.
